This invention is designed to completely cleanse and sterilize bed pansrelieving the operator of inconvenient handling. Features of theinvention will appear from the specification and claims.

The invention is illustrated in the accompanying drawings as followsFig. 1 shows a side elevation, a part being broken away to show theconstruction.

Fig. 2 a central section on the line 22 in Fig. 1.

Fig. 3 a section of a portion of the device on the line 33 in Fig. 2.

1 marks the case, 2 the cover 3 a lifting leer cast on the cover l pushrod for lifting the cover, 5 a pedal by means of which the cover islifted with the foot. The case is provided with the usual discharge trap6 leading to the sewer and the usual vent pipe 6 also preferably leadingto the sewer.

A rod 7 extends across the upper part of the case and is journaled atone end in a bearing 8 and extends through a bearing 9 at the oppositeside of the case. A platform or frame 10 is fixed on the shaft 7. It hasthe stop fingers 11 adapted to engage the open end of the pan. Clampingfingers 12 and 13 are pivotally mounted by pivots 12 and 13 on blocks 1%and 15 secured to the rod 7. Links 16 connect the clamping finger 12with a ring 17 slidingly mounted on the bearing 9. A spring 18yieldingly forces the ring against a stop 19 at the end of the bearing.A spring 20 is arranged in the bearing 8 and tends to hold the rod inthe central position against a stop formed by a handle hereinafterdescribed.

A link 21 is connected by a pivot 22 with the clamping finger 12 belowthe pivot 12 and at the opposite side of the pivot 12 from theconnection of the link 16. The link 21 is pivotally connected at 23 tothe Serial No. 743,826.

clamping linger 13 above the pivot 13. Tfith this ar i 'ement of pivotswhen the clamping linger 12 is closed on the pan it rocks the clampinglinger 13 simultaneously into engagement with the pan.

have provided a mechanism so that when the pan is tilted for emptyingit, by swinging sh 7 th shaft 7 is also moved endwise, t

nus moving the clamping lingers automatically into engagement with thepan and so holding it.

A handle 21- is pivotally mounted by a in on the end of the shaft 7. Ithas a rejection 26 which rides on an end 27 of c cam sleeve 28projecting from the hearing The handle projects through a cam slot inthe sleeve 28. 51s the handle is swung the end 26 rides on the end 27and the cam 29 operating on the handle as it turns the rod 7 moves the0d outwardly against "he tension of the and this outward movement of therod 7 swi s the clamping fingers 12 throu h the a ti n into engagementwith the pan and at the same time carries the finger 13 into engage mentwith the pan. The spring 18 yields slightly the extreme movement so asto adjust the fingers to different sizes'of pans. A cover case 30 isarranged around the sleeve 28. This has a slot 31 for permitting themovement of the handle.

The flushing mechanisn is "Vs-ale: is supplied from a pipe 32. pipe 33leads from the pipe 32 ring The flushing ring is a series of jets towardthe cen er or t of jets 86 ertending adapted to cleanse the of case. l ihen the pan is in the horizontal position shown in Fig. 2 the water isturned into the jet ring by the opening of the valve The converging jetsmeet at the center d thus neutralize the ets so that the we from thesejets drops directly into the pan filling the same and thus facilitatesthe flushing of it. After this is done the pan is tilted to ninetydegrees to the position shown in Fig. 3. lVater is delivered by a pipe38 from the pipe 32 to a flush valve 39 as follows A branch downwar ofthe usual type automatically closing with a desired interval afteropening. s is operated b a handle 40. The water passes from the ushvalve 39 through a pipe -11 past the check "alve and branch pipe. id tothe jet openings 45. These jet openings cross each other being directedso as not to interfere with each other and also are inclined upwardly,their direction being such as to strike the curl of the bed pan andentirely flush and clean the same.

After the flushing is mpleted steam is delivered by way of the pipe 46to the pipe 43, the steam being controlled by a valve ii. The checkvalve prevents the entrance of the steam to the water passages. he jetsof steam following the same directions as the jets of water areprojected into and against the curl or wall of the bed pan and are thusdeflected over the entire pan, thus entirely cleaning and sterilizingthe same. After the steaming the pan swung to the upright position andas it is swung the clamps are released, the cover is opened, and he panbeing entirely clean and sterilized may be conveniently removed.

\Vhat I claim as new is 1. In a bed pan cleaner, the combination of aclosed case; a pan frame in the case; a shaft on which the frame ismounted; clamping fingers pivotally mounted on the shaft; a linkconnecting the fingers and communicating movement from one to the other;and means operating on one of the lingers to clamp the pan on, theframe.

2. In a bed pan cleaner, the combination of a closed case; a tiltingframe in the case; means in the case adapted to clamp a pan on theframe; and mechanism for operating 5 said means to clamp and release apan on the frame, said mechanism extending from said means to withoutthe case and operable outside the case.

3. In a bed pan cleaner, the combination of a closed case; a tiltingframe in the case;

means extending from the frame to without the case for tilting theframe, said means being operable outside the case; devices adapted toclamp a pan on the tilting frame; and mechanism connected with saiddevices and automatically actuated as the frame is tilted for actuatingsaid devices.

4. In a bed pan cleaner, the combination of a closed case; a shaftrotatively and slidingly mounted in the case; a pan supporting framemounted on the shaft; means operating on the shaft and extending towithout the case for imparting a rotating and endwise movement to theshaft; devices for w clamping the pan on a frame; and mechanismautomatically actuated as the shaft is moved endwise actuating saiddevices.

5. In a bed pan cleaner, the combination of a closed case; a pansupporting frame; a shaft mounted in the case; a lever outside the caseconnected with the shaft and o crable outside the case to rotate the shat; a cam mechanism for moving the shaft endwise as it is rotated;devices for clamping a pan on the frame; and means actuated by theendwise movement of the shaft actuating said devices.

6. In a bed pan cleaner, the combination of a closed case; a pansupporting frame;

a shaft on which the frame is mounted, said' shaft being rotativelymounted in the case; a lever connected with the shaft and extendingoutside of the case and outside of the shaft to rotate the shaft; a cammechanism for moving the shaft endwise as it is rotated; devices forclamping a pan on the frame comprising a spring imparting yieldingaction to the clamping devices; and mechanism for actuating said devicesas the shaft is moved endwise through the action of the cam mechanism.

7. In a bed pan cleaner, the combination of a closed case; a pansupporting frame in the case; a shaft mounted in the case on which theframe is mounted; clam ing fingers pivotally mounted on the sha t; alink connecting the fingers to communicate movement from one to theother; means for actuating the fingers comprising a yielding springimparting yielding clamping action to the fingers; and devices actingthrough the shaft on said means to actuate the fingers.

8. In a bed pan cleaner, the combination of a closed case; a pansupporting frame in the case; a shaft rotatively mounted in the case andon which the frame is mounted; clamping fingers pivotally mounted on theshaft; a link connecting the fingers and communicating movement from oneto the other; devices for acting on the fingers to operate the same;means for rocking the shaft; and mechanism automatically actuated as theshaft is rocked for actuating said devices.

9. In a bed pan cleaner, the combination of a closed case; a tilting pansupporting frame; a jet ring having jet openings therein, said jetopenings having directions in lines converging toward a point over a panon the frame; and means directing an upwardly inclined jet against atilted pan on the frame.

10. In a bed pan cleaner, the combination of a closed case; a tiltingpan frame therein adapted to support a pan spaced from the walls of thecase; means for tilting the pan frame; and a jet ring having jetopenings therein, said jet openings having directions in linesconverging toward a point immediately above a pan on the frame.

In testimony whereof I have hereunto set my hand.
